Short answer
Kiting and windsurfing load the lower back through the harness for hours, often leaning back against strong south-easter gusts. Back pain is usually muscle and joint overload from long sessions early in the season, a harness that rides up, or a lot of pumping and uphauling. It usually settles with shorter sessions, harness adjustments and trunk and hip strength on land.

Common causes
Harness position
A waist harness that rides up loads the lower ribs and back; a seat harness spreads load lower.
Session length
Long downwinders and the first windy weeks of summer after months off.
Pumping and uphauling
Windsurfers repeatedly lift the rig and pump in light wind, which loads the back in flexion.
What usually helps right now
- Shorten sessions for a week or two and take breaks on the beach.
- Check harness fit and spreader bar height; try a seat harness if a waist harness rides up.
- Add trunk, glute and hip strength work on land.
- Walk and move gently on rest days.
What to avoid
- Back-to-back full days in the first week of the season.
- Uphauling repeatedly with a sore back; use a beach or water start.
- Ignoring pain that spreads into the leg.
When to book an assessment
- Back pain lasts more than a week after kiting or windsurfing.
- You want to be ready for the windy season.
Get urgent medical care if
- Leg numbness or weakness, or changes in bladder or bowel control: seek urgent care.
- Back or neck injury after a crash or being dragged: seek medical care.
How we treat it
- AssessHistory, movement and clinical tests, with screening for anything that needs a doctor.
- ExplainA clear diagnosis in plain language, and what recovery usually looks like.
- TreatHands-on care where it helps: joint and soft tissue work, dry needling or adjustments.
- RebuildExercises and a training plan so it holds up, with an end point.
Questions
Is a seat harness better for back pain?
Many riders with back pain find a seat harness more comfortable because it spreads load lower. Fit matters more than type.
Can I kite with lower back pain?
Usually yes, with shorter sessions and lighter wind days while it settles.
